Solución

Ha introducido [src]
a*x = 20 + a
$$a x = a + 20$$
Solución detallada
Tenemos una ecuación lineal:
a*x = 20+a

Dividamos ambos miembros de la ecuación en a
x = 20 + a / (a)

Obtenemos la respuesta: x = (20 + a)/a
Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$a x = a + 20$$
Коэффициент при x равен
$$a$$
entonces son posibles los casos para a :
$$a < 0$$
$$a = 0$$
Consideremos todos los casos con detalles:
Con
$$a < 0$$
la ecuación será
$$- x - 19 = 0$$
su solución
$$x = -19$$
Con
$$a = 0$$
la ecuación será
$$-20 = 0$$
su solución
no hay soluciones
